Sole trader or limited company: how psychologists in Ireland structure a private practice

By Nerela · Published 23 September 2026 · 6 min read

Before you see your first private patient, one quiet decision shapes almost everything else about your paperwork: do you trade as yourself, or set up a separate company? Neither is universally "right" — but the two paths are genuinely different in how they're registered and what they commit you to. This is the structural picture, not tax advice for your specific numbers.

This isn't tax advice. Figures, rates and thresholds change and depend on your personal circumstances — always confirm the current position with an accountant before you register anything. What follows is the structural picture: how each option works, not what either one will cost you specifically.

Sole trader: the simpler starting point

Most psychologists starting a private practice in Ireland register as a sole trader. In practice, that means:

Limited company: a separate legal entity

A limited company is registered with the CRO as its own legal entity, distinct from you personally. That brings:

How to actually decide

This is genuinely a case-by-case decision, and the honest answer is "it depends on your numbers and your accountant's advice" rather than a rule of thumb that applies to every practice. Questions worth bringing to that conversation:

  1. What's your realistic income in year one, and how might that change over the next few years?
  2. How much does the extra administration of a company genuinely cost you in accountancy fees, against whatever benefit it brings?
  3. Are you planning to grow into a multi-practitioner centre, where a company structure may fit more naturally?
  4. How much does personal liability protection actually matter for the specific risks in your practice?

Many practices start as a sole trader while building a patient base, and incorporate later once the picture — and the reasons for changing — are clearer. Starting simple isn't a mistake; it's often the sensible default while you find out what your practice actually looks like in practice.

Whichever structure you choose, the invoicing side is the same

See how Nerela issues invoice-receipts either way, with the right details on each one.

What doesn't change either way

Whether you trade as a sole trader or through a company, some things stay the same: Ireland doesn't currently require certified e-invoicing for psychologists, VAT registration is a separate question to confirm with your own accountant regardless of structure, and professional indemnity insurance matters just as much either way. Nerela issues a PDF invoice-receipt with your (or your company's) details, automatic sequential numbering, and a card payment link, whichever structure you're trading under — and at €19/month for a solo psychologist, with 14 days free and no card, it's worth setting up before the paperwork side becomes its own project.

Frequently asked questions

What's the simplest way to start seeing private patients in Ireland?+

Registering as a sole trader is the most common starting point: you register for income tax as self-employed with Revenue, and you can trade under your own name or register a business name with the Companies Registration Office (CRO) if you want to trade under something else. It's simpler to set up and to wind down than a company, with comparatively little ongoing filing.

When does a limited company start to make sense?+

There's no single trigger that applies to everyone — it depends on income level, growth plans, and how you and your accountant weigh liability protection against the extra administration a company brings (CRO filings, separate company accounts, director obligations). It's a conversation worth having with an accountant looking at your actual numbers, ideally before you need the answer under pressure rather than after.

Does registering as a sole trader affect how I invoice patients?+

Not fundamentally — either structure can issue an invoice or receipt to a patient. What changes is whose name and registration details appear on it: your own as a sole trader, or the company's if you've incorporated. Ireland doesn't currently require certified e-invoicing for psychologists, and VAT registration is a separate question to confirm with your own accountant regardless of which structure you choose.

Can I switch from sole trader to a limited company later?+

Yes, and many practices do exactly that — starting as a sole trader while building a patient base, then incorporating later once the numbers and the reasons for doing so are clearer. It's a bigger administrative step to change structure than to pick one at the outset, so it's worth planning the transition with an accountant rather than doing it reactively.
